IPC: H02P23/14
Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To compute inertia through simple constitution without an occurrence of regeneration and drive a motor. SOLUTION: To compute inertia J, first, the motor is run at a speed of ω1 and is thereafter accelerated for the first time at an acceleration rate of (ω2-ω1)/Δt12 for Δt12 (=T0/n1) seconds from time t1 to time t2. During this period, the motor torque τm is computed and subjected to time integration. Δt12 seconds later, the result of the integration is stored. Then, the motor speed is changed to ω3, where ω3=ω1. Thereafter, the motor is accelerated for a second time at an acceleration rate of (ω4-ω3)/Δt34 for Δt34 (=T0/n2) seconds from time t3 to time t4. The integration start speed and the integration end speed are the same as in the first-time acceleration, but the acceleration rate is changed (ω3=ω1, ω4=ω2, Δt12≠Δt34).  During acceleration, the motor torque τm is computed and subjected to time integration. Δt34 seconds later, the result of the integration is stored. Last, inertia J is computed using the results of the first- and second-time integrations.
